Enable scaling to fit various screen resolutions
Since the AGL HomeScreen of CES2018 assumes that the screen resolution is 1080x1920px, the graphics of it partially corrupted with others. To fix this issue, now the AGL window manager automatically scales size according to "scaling" value in setting.json By default(even if "scaling" is not set), this scaling keeps 'fullscreen' aspect rate in area.db("aspect_fit") User can select 3 options. - "aspect_fit" : Scale aspect rate of 'fullscreen' in area.db.(default) - "display_fit": Force to scale to display size. - "none" or others : Set size just as area.db Bug-AGL: SPEC-1568 Bug-AGL: SPEC-1569 Change-Id: Ia08c0ebb2d71ae8f89a90088e181381c3ba3562d Signed-off-by: Kazumasa Mitsunari <knimitz@witz-inc.co.jp>
